Besides, the invention generally relates to the use of the compounds of the formula I for increasing the resistance of plants to the phytotoxicity of agrochemicals.

Agrochemicals for the purposes of the present invention include in particular fertilizers or herbicidal, growth-regulatory, fungicidal, insecticidal or nematicidal crop protection products.

The compatibility of crop plants with agrochemicals is not always entirely sufficient, i.e. not only a desired growth-promoting, herbicidal, growth-regulatory, fungicidal, insecticidal or nematicidal effect is observed, but in some cases the crop plants are damaged to an extent which is unacceptable. Another undesired side effect of herbicidal, fungicidal, insecticidal or nematicidal crop protection products can be a growth-inhibitory effect. Reducing the application rate of the agrochemical, which is generally desired, has the disadvantage that, while the crop plant remains unharmed, the desired herbicidal, fungidical, insecticidal or nematicidal action is insufficiently achieved. The symptoms of the damage range from morphological modifications via growth inhibition to death of the plants (phytotoxicity).

Controlling such symptoms of damage is extraordinarily difficult owing to the multiplicity of the causes of damage brought about by agrochemicals; preventative measures are therefore the main priority. Accordingly, increasing the resistance of plants to the phytotoxicity of agrochemicals is an important demand in agriculture.

It was an aim of the present invention to provide a method which can be used widely, which does not damage the plants and which brings about an efficaceous increase in the resistance of the plants to the phytotoxicity of agrochemicals.

Accordingly, the method defined at the outset has been found. The active ingredients of the formula I which are used are known as fungicides and in some cases also as insecticides (EP-A 178 826; EP-A 253 213; WO-A 93/15046; WO-A 95/18789; WO-A 95/21153; WO-A 95/21154; WO-A 95/24396; WO-A 96/01256; WO-A 97/15552; WO-A 97/27189). However, a potential effect of these active ingredients with regard to increasing the resistance of plants to the phytotoxicity of agrochemicals has not been mentioned as yet.

Active ingredients which reduce undesired side effects of other agrochemicals are usually termed “safeners”. The use of the active ingredients of the formula I as safeners is novel.

The good tolerance by plants of the active ingredients of the formula I at the concentrations required for controlling plant diseases permits the treatment of aerial plant parts and also the treatment of propagation material, seed and of the soil.

In the method according to the invention, the active ingredient is preferably taken up via the roots of the plants and distributed throughout the plant with the sap.

This is why the effect after using the method according to the invention is not only observed in those plant parts which were sprayed directly, but the resistance to the phytotoxicity of agrochemicals is increased throughout the plant.

In a preferred embodiment of the method, the subterranean plant parts are treated with a formulation of the active ingredient I.

In another preferred embodiment of the method, the seed is treated with a formulation of the active ingredient I.

The compounds I increase the resistance of the plant to the phytotoxicity of agrochemicals. They are especially important for the treatment of various crop plants such as wheat, barley, rye, oats, rice, golf turf, maize, bananas, cotton, soya, coffee, grapevines, fruit species and ornamentals, and vegetable species such as cucumbers, beans, tomatoes, potatoes and the pumpkin family, and on the seeds of these plants, in particular wheat, barley, rye, oats, maize and rice.

Specifically, they are suitable for controlling the following symptoms of damage:

-   -   reduced plant height in rice, cereals or tomatoes,     -   development of necroses in dicotyledonous crops such as         cucumbers or grapevines,     -   deformation of the leaves in wheat, cucumbers or tomatoes,     -   discoloration of the green leaf tissue, such as, for example,         bleaching in barley or soya,     -   wilting symptoms despite adequate nutrient supply.

The compounds I are applied by treating the plants to be protected, seeds or the soil with an effective amount of the active ingredients. Application can be effected both before and after application of the phytotoxic agrochemical to the plants or seeds.

In a preferred embodiment of the method, the plant is treated concomitantly with the application of the other (phytotoxic) agrochemical. A markedly reduced susceptibility of the plant to the phytotoxicity of the other agrochemical is observed.

Agrochemicals are understood as meaning essentially the herbicidal, acaricidal, insecticidal, nematicidal and fungicidal substances listed on the Internet under http://www.hclrss.demon.co.uk/index_cn_frame.html (index of common names). In particular, the active ingredients of the formula I are applied together with herbicidal, acaricidal, insecticidal, nematicidal or fungicidal agrochemicals selected from the list which follows:

When used in crop protection, the application rates are between 0.01 and 2.0 kg of active ingredient per ha, depending on the climatic conditions and the nature of the phytotoxic agrochemical and the plant.

In the treatment of seed, the active ingredients are generally required in amounts of from 0.001 to 0.1 g, preferably 0.01 to 0.05 g, per kilogram of seed.

The compounds I can be converted into the formulations conventionally used for fungicides, for example solutions, emulsions, suspensions, dusts, powders, pastes and granules. The use form depends on the intended use; in any case, it should ensure that the compound according to the invention is distributed finely and evenly.

The formulations are prepared in the known manner, for example by extending the active ingredient with solvents and/or carriers, if desired using emulsifiers and dispersants, it also being possible to use other organic solvents as cosolvents if water is used as the diluent. Adjuvants are essentially those which are also conventionally used for fungicides. In general, the formulations comprise between 0.01 and 95% by weight, preferably between 0.1 and 90% by weight, of the active ingredient. The active ingredients are employed in a purity of from 90% to 100%, preferably 95% to 100%-(according to NMR spectrum).

Examples of formulations are known from the publications cited at the outset.

Aqueous use forms can conventionally be prepared from emulsion concentrates, pastes or wettable powders (sprayable powders, oil dispersions) by adding water. To prepare emulsions, pastes or oil dispersions, the substances, as such or dissolved in an oil or solvent, can be homogenized in water by means of wetter, adhesive, dispersant or emulsifier. It is also possible to prepare concentrates composed of active ingredient, wetter, adhesive, dispersant or emulsifier and, if appropriate, solvent or oil, and these concentrates are suitable for dilution with water.

The active ingredient concentrations in the ready-to-use preparations can be varied within substantial ranges. In general, they are between 0.0001 and 10%, preferably between 0.01 and 1%.

The active ingredients can also be used successfully in the ultra-low-volume method (ULV), it being possible to apply formulations with over 95% by weight of active ingredient or even the active ingredient without additions.

Various types of oils, or herbicides, other fungicides, other pesticides, or bactericides may be added to the active ingredients, if appropriate also just prior to use (tank mix).

These agents can be admixed to the agents according to the invention in a weight ratio of 1:10 to 10:1.

The information regarding the use according to the invention of the active ingredients I can be printed on the packaging or be provided in product data sheets. This information can also be provided in the case of products which can be applied in combination with the active ingredients I.

Use examples for increasing the resistance of the plants to the phytotoxicity of agrochemicals.

The active ingredients were prepared separately or jointly as a 10% emulsion in a mixture of 85% by weight of cyclohexanone, 5% by weight of Nekanil® LN (Lutensol® AP6, wetter with emulsifying and dispersing action based on ethoxylated alkylphenols) and 10% by weight of Wettol® EM (nonionic emulsifier based on ethoxylated castor oil) and diluted with water to give the desired concentration.

USE EXAMPLE 1 Effect of Active Ingredients and their Combinations on Plant Growth

Rice cv. “Koshihikari” was sown in a seedbox and grown for 24 days under controlled warm and moist conditions in controlled-environment cabinets and in the greenhouse. Two days before the rice was transplanted into the field, each of the seedboxes was sprayed to runoff point with preparations of the active ingredient in the concentrations mentioned hereinbelow in the form of an aqueous suspension made with a stock solution consisting of 10% active ingredient, 85% cyclohexanone and 5% emulsifier. The seedboxes were subsequently cultured in the greenhouse for a further 2 days until the rice was manually transplanted into the field at a rate of 5 clumps per m².

Three weeks after the treatment, the plant height of the rice clumps was measured and compared with untreated rice plants. The extent of plant stunting is a measure for the plant-damaging effect of substances on the root system.

The “phytotoxic agrochemical” used in the present example was the active ingredient [5-chloro-6-(2,4,6-trifluorophenyl)-[1,2,4]triazolo[1,5-a]pyrimidin-7-yl]-((S)-2,2,2-trifluoro-1-methylethyl)amine, which is disclosed in WO-A 98/46608 (compound A).

In this experiment, 15% stunting was observed in the rice plants treated with 200 g of active ingredient A per hectare, no dwarfing in the rice plants treated with 400 g of active ingredient I-16 per hectare, and 6% stunting in the rice plants treated with 600 g/ha active ingredient I-16. Only 6% dwarfing was observed in the plants treated with 200 g/ha active ingredient A and 600 g/ha active ingredient I-16, while only 3% dwarfing was observed in the plants treated with 200 g/ha active ingredient A and 400 g/ha active ingredient I-16.

USE EXAMPLE 2 Effect of Active Ingredients and their Combinations on the Herbicidal Activity

The “phytotoxic agrochemicals” used in this example were the active ingredients [3-(4,5-dihydroisoxazol-3-yl)-4-methane-sulfonyl-2-methylphenyl]-(5-hydroxy-1-methyl-1H-pyrazol-4-yl)-methanone (compound B) and 4-(3-trifluoromethylphenoxy)-2-(4-trifluoromethylphenyl)pyrimidine (compound C), which are disclosed in WO-A 98/31681 and EP-A 723 960, respectively:

The safening effect of the compounds of the formula I on compounds B and C which were used as examples was demonstrated in the following experiment:

The culture containers used were plastic pots containing loamy sand with approximately 3.0% humus as substrate. The seeds of the test plants were sown separately for each species.

For the treatment, the test plants were first grown to a plant height of 3 to 15 cm, depending on their habit, and then treated with the active ingredients which were suspended or emulsified in water. The test plants were grown separately as seedlings and transplanted into the experimental containers a few days before the treatment.

Depending on the species, the plants were kept at temperatures of from 10 to 25° C. or 20 to 35° C. The experimental period extended over 2 to 4 weeks. During this time, the plants were tended, and their response to the individual treatments was evaluated.

The phytotoxicity was evaluated using a scale of from 0 to 100. In this context, 100 means complete destruction of at least the aerial parts, and 0 means no damage or normal course of growth.

The plants used in the greenhouse experiments were composed of the following species: Latin name English name Code Oryza sativa rice ORYSA Echinochloa barnyardgrass ECHCG crus-galli Triticum aestivum spring wheat TRZAS Chenopodium album pigweed CHEAL Pharbitis morningglory PHBPU purpurea
